This is different than what I'd been envisioning -- I was under the
impression MyModel.objects wouldn't contain state. A manager shouldn't
contain state of the filter() queries that were passed to it. (This is
a good argument for treating managers differently than many-to-one and
many-to-many QueryResult objects.)
